Abstract

The present invention configures the receiving end like the current wireless pager and, unlike the current pager, does not display the text information on the LCD screen, and reads it from the microprocessor, and if it matches the set function and password, the pager processes the set function. This is an anti-theft detection device used. When a theft occurs, the voice synthesizer is controlled to transmit vehicle characteristic voice data (color, car model, number) repeatedly to the police radio frequency band until it is released. It is received from the police radio or a specific decryption device.) This device has a switch that connects the receiver circuit of the pager and the internal antenna and sets a password. Password and function number fixed externally and set externally When it is called, the operation corresponding to each function number can be operated.In case of theft, the voice synthesizer is controlled by the data of the vehicle characteristic setting switch value (color, model, number) to synthesize the voice (eg “Black Le Mans race 2440 stolen vehicle”). Action wind ”) It propagates through the transmitting circuit, and at the same time, it encodes the data so that it can be displayed by text and mixes it with the voice signal, which has the characteristic of repeatedly propagating until the vehicle owner releases it by telephone. have.

That is, the present invention is a car theft arrester, not an existing car antitheft device, but rather a complete arrest after theft rather than the current prevention of theft. In order to prevent this, the car thief must not know whether the device is installed in the device, so unlike the existing anti-theft device, instead of flashing the lamp or sounding the siren, The invention is characterized by the possibility of early arrest of a criminal by wirelessly notifying vehicle characteristic data that has appeared in police, checkpoints, and patrol cars within tens of meters of the vehicle.

Claims (4)

In the anti-theft detection device of a remote controlled vehicle, a receiving end is composed of a high frequency amplifier circuit 22, a detection circuit 23, a decoder, and a comparison circuit 24, such as a wireless pager, and the received data is read by the microprocessor 37. An anti-theft detection device using a wireless pager that handles a set function when the value of the set function and the password setting switch 33 is matched. When a theft occurrence report function, vehicle characteristic voice and digital data (color, model, number) are specified. Turn on the circuit power supply control relay 25 to supply power to the voice synthesizer and the transmitting circuit encoding circuit so as to be repeatedly transmitted until the release signal comes in. The color setting switch 34 and the vehicle type setting switch 35 , The vehicle number setting switch 36 is read, and the voice data of the voice memory 26 corresponding to each value is read and synthesized by the voice synthesis IC 31 and simultaneously encoded. In (32), each data value is converted in series, mixed with the preceding voice signal and the mixer 27, modulated by the high frequency signal generated by the high frequency oscillation circuit 39 and the modulation circuit 40, and the high frequency amplification circuit 28. After the amplification in the car theft arrest apparatus using a radio calling method, characterized in that configured to propagate through the antenna 21 via the transmission circuit (38). 2. A radio frequency amplification circuit as claimed in claim 1, comprising a decoding apparatus for displaying a text message on a liquid crystal and transmitting an alarm sound to inform the police of a vehicle so as to inform the police of vehicle characteristic data. After amplifying by 41, the high frequency signal and the encoded characteristic setting signal are separated through the demodulation circuit 42, amplified by the amplifying circuit 43, and the microprocessor 47 through the decoder IC 44. Reads the signal from the LCD, displays the color, model, and number on the liquid crystal module 48, drives the buzzer and the lamp 52, receives the digital characteristic data code, and controls the voice synthesis IC 46 and the voice memory 45. A decryption apparatus for an anti-theft arrest apparatus using a wireless calling method, characterized by synthesizing a vehicle characteristic voice and amplifying it (49) through a speaker (50). According to claim 1, Instead of setting the vehicle characteristic data to a dip switch, the reception data of the pager is a function number three digits, a password four digits, a color number one digit, a model number two digits, an area code two digits, a car number A method for setting a vehicle characteristic code comprising four digits and a total of 16 digits. ※ Note: The disclosure is based on the initial application.
